You don't lose $1000 for incinerating, just for delivering the wrong good. But yes you have to be careful, we wanted players to have a machine that guaranteed delivered the right goods but maybe incinerated some of the right goods as well because we thought that was the most fun to play. I think that it's not the perfect or most balanced system, but it works pretty well for a jam game. When testing out early game I usually just blocked off the delivery area, or paused production, and then built my system with an Xray at the end to be sure it worked. After the early game I found that a few wrong deliveries usually didn't mean the game was over and you just needed to block off an exit for a while. All of this of course doesn't mean anything because I already know how the game works so I don't need to experiment like a new player haha. Either way thanks so much for the kind words, we're pretty happy with it!
